pests in Australia

see also:

  • cane toads
  • flies
    • most native fly species in Australia are benevolent
    • March flies are a major nuisance as their proboscis hurts when they stick it into your skin
    • Australian bush flies are a nuisance due to their sheer numbers in summer and tendency to try to get protein from your tears
      • their populations can rapidly expand in hot humid conditions
    • "sand flies" / biting midges are a nuisance in many areas as they are tiny at 1-4mm but bite causing itchy reactions
    • fruit flies are a pest to fruit growers
    • the introduced species are a pest:
      • house fly - spits out digestive fluids onto food before eating it and in the process spreads pathogens
      • sheep blowfly - from Sth Africa causes major issues for the sheep industry with their maggots
  • European wasps (Vespula germanica)
    • these imported, aggressive pests tend to be mainly a problem in relatively dry inland areas
    • in some regional towns they can be a real problem as they feed off newly dead insects on car grills when they park at shopping centres - example towns include Yea, Yackandandah, Tumbarumba
    • they also feed on honeydew and honey and will often swarm around BBQ meats
    • the colonies including the queen generally die off over winter (although some may survive in milder winters of Australia), after winter hibernation the surviving daughter queens build a nest and rear the 1st brood of workers in spring which emerge as adults within ~30 days of hatching
    • they need a body temperature of at least 22degC to fly which equates to an ambient temperature of at least 8degC 1), in contrast the minimum temp for honey bees is around 12degC.
  • mice
    • mice plagues often occur in inland Australia in particular after flood events along the Murray River
    • mice, when in large numbers can cause havoc with campers - mouse urine on canvas, holes eaten in canvas, etc
    • keep all food enclosed and try green camphor moth balls as deterrents
    • exposure to rodent urine does run the risk of catching the serious infection leptospirosis
